Resumen de The heat is on
Cascio talks about the importance of the solar radiation management (SRM). SRM adds particles to the upper atmosphere to reflect a small fraction of incoming sunlight, potentially slowing, halting or reversing global warming. Researchers at Harvard University are about to launch a project in the sky above Arizona to see if it works for real. The test will be too small to alter global temperatures, but it still amounts to the biggest trial of the method. Those studying geoengineering emphasize that this technique, although potentially quick and relatively cheap, would not offer a permanent fix. It would be a climate tourniquet to temporarily stem rising temperatures
